Chuchani is most known for his important research in homogeneous, unimolecular gas phase pyrolysis or elimination of organic molecules and, in particular, about their mechanisms. Through this work, he has provided highly reliable data and a number of challenging problems to quantum chemistry, reaction kinetics, and organic reactivity. Conceptually, his research has broadened the area of mechanistic organic chemistry to the gas phase, where it can be connected to gas phase ion chemistry. He is emeritus professor in Chemistry, Instituto Venezolano de Investigaciones Científicas (IVIC) in Caracas, Venezuela. He has received several international and national awards, including Venezuela's Premio Nacional de Ciencia, and is a member of many scientific academies and societies.
